SPECIFICATION forming partof Letters Patent No. 513,198, dated J anuary 23, 1894.

Application filed Qeptember 5, 1898. SerialNo. 484,862. (No model.)

To wZZ whom it may concern.-

Be it known that I, HARRISON PITTMAN, a citizen of the United States, residing at Industry, in the county of McDonough and State of Illinois, have invented a new and useful Check-Row Corn-Planter, of which the following is a specification.

My invention relates to improvements in check-row corn-planters, the objects in'view being to provide asimple, durable, and inexpensive mechanism or attachment for the ordinary check-row corn-planter, whereby the same is designed to operate through the medium of the check-wire, the seed-mechanism, and accurately and eiiiciently drop seed; and, furthermore, to provide for an adjustment of the check-row mechanism, whereby the reciprocations of the seed-slide may be regulated.

With these and other objects in view the invention consists in certain features of construction hereinafter specified and particularly pointed out in the claims.

Referring to the drawings:Figure 1 is a perspective view of a portion of a corn-planter embodying my invention. Fig. 2 is a central transverse vertical-sectional view. Fig. 3 is a longitudinal sectional view of the camsleeve. Fig. 4. is a detail in perspective of the vibrating arm. Fig. 5 is a detail in perspective of one of the forked arms.

Like numerals of reference indicate like parts in'all the figures of the drawings.

Any ordinary corn-planter frame may be employedin connection with my invention, and I have shown the same as applied to one of the usual forms, or rather have'illu'strated it in connection with so much of such framework as is necessary to illustrate the application of the device.

The framework 1 has mounted thereon the usual hoppers 2, in whose bottoms is located the transversely reciprocal seed-slide 3. The hoppers are connected, in the present instance, by front and rear bars 4, to render the same steady, and produce in connection with the hoppers an intermediate opening. From each hopper there rises at the outer end an inverted L-shaped standard 5, and each standard supports a cross-bar 6, the said cross-bars having intermediate transversely opposite bearings 7 in which is mounted for rotation a transverse shaft 8. The transverse shaft 8 has its ends extending beyond its bear-.

ings, and has applied thereto and adapted for rotation therewith the forked arms 9, which, as shown, are slotted or bifurcated at their opposite ends. These forked arms are further provided upon their inner sides with pairs of pins 10 arranged diametrically opposite each other, and flat springs 11 are secured to the arms and bear upon the springs "so that as the forked arms revolve with the shaft, each pin is brought under, elevates, and passes by the aforesaid springs. Q A pair of short stub-shafts 12 and single stub-shafts 13 extend from each hard in front, and in rear, respectively, of the said shaft 8, and these shafts carry grooved rollers let which are in line with the bifurcations of the forkedarms. A check-wire 15 passes under the front roller, over the next, through the forked-arms, and over the rear rollers, as shown by dotted lines, Fig. 1. cupied by a cylindrical casting 16, the same having a bore 17 formed therein, which, as shown, is diagonally or at an angle to the axis of said casting. The exterior of the casting is provided at each side of its center with integral, annular bosses. 18, and a bindingscrew 19 passes through the casting beyond one of the collars and serves to secure the same upon the aforesaid shaft. A pitman arm 20 is provided witha half-bearing 21 that fits the rear side of this cylindrical casting, and a block 22, through the medium of screws 23, is provided with a half-bearing 24 which clamps the opposite or front side of said casting, the said pitman as a whole being loose. The pitman extends below the block and is provided with a channel25 in its front face within which a series of holes 26 is formed. An L-shaped arm or bracket 27 is, through the medium of a screw 28, adjusted in the channel and to any of its holes, and has its lower horizontal portion provided with a series of perforations 29, any one of which ongages with a vertical pin 30 projecting from the seed-slide 3. Byreason of the seriesof holes in the lower portion of the bracket or L-shaped arm, the attachment can be fitted. to any of The center of the shaft is ocof its .bore, the pitman and bracket-arm, and the latter reciprocates the seed-slide, d rapping the seed at proper intervals.

From the foregoing description in connection with the accompanying drawings it will be seen that I have provided a very simple construction of attachment that may be applied to any ofthe ordinary corn-planters now in use thatinclude in their make-up a transversely reciprocating slide. It will furthermore be seen that'I do not employ any fragile parts, wheels, or gears that are liable to become impaired or broken. 7

By reason of-the fiat springs that operate upon the pins of the forked arms it will be seen that the forked-arms are moved-intermittingly, that is, only when engaged by a button on thecheck-wire, the springs serving to steady the forked arms, their shafts, and the partspperated thereby.

I do not limit my invention to the precise details ofconstruction herein shown and described, but hold that I may vary the same to knowledge and the bars, of atransverse shaft journaled in the bars, bifurcated forked arms'arranged on the opposite ends of the shaft, pins at the inner ends of the forked arms, flat springs arranged in the paths of the pins, check-wire guides in front and in rear of the forked arms, and motion conveying devices between the shaft and theseed-slide,substantially as specified. 2. The combination with the opposite hoppers, the opposite superimposed bearings, the seed-slide arranged for movement under the hoppersand having an intermediate vertical pin, of the transverseshaft arranged in the bearings, the diagonally bored sleeve mounted on the shaft and rotating therewith, the pitlnan-arm and block secured together each having a half bearing receiving a bored sleeve, and an L-shaped bracket arm engaging the pin of the slide'and adj ustably mounted on the lower end of the pitman-arm, substantially as specified.

In testimonythat I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
